Is this the dBASE ProgressBar object, or is it in the installer that the 
issue occurs ...? If it's the installer, that's not actually a dBASE 
product, but InstallShield (I think) ...

The v2.61.4 patch kit's progress bar on Vista does not work when the aero UI is
enabled. It starts and stays at 100%.

I have seen this before and it is an incompatibility with the dBPLUS progress
object that needs some settings in

Good point ... in this case the installer.

I have already seen the same problem with the dBase progress object in v2.61.3
and changed my visual effects setup and modified my progress bar update code to
workaround it.

Hi Andrew. I have been unable to recreate the issue using Vista Aero 
with a simple progress bar (see below).
Are you seeing the same issue with this sample?
If not, Can you provide a turnkey for the issue you are seeing?

parameter bModal
local f
f = new progressvistaForm()
if (bModal)
   f.mdi = false // ensure not MDI
   f.readModal()
else
   f.open()
endif

class progressvistaForm of FORM
   with (this)
      onOpen = class::FORM_ONOPEN
      height = 16.0
      left = 82.5
      top = 0.0
      width = 40.0
      text = ""
   endwith

   this.PROGRESS1 = new PROGRESS(this)
   with (this.PROGRESS1)
      height = 1.0
      left = 6.0
      top = 6.7273
      width = 24.4286
      value = 0
      rangeMin = 0
      rangeMax = 10
   endwith


   function form_onOpen
      for x = 1 to 10
         sleep 1
         form.progress1.value = x
      endfor
      return

endclass

Thanks, Kathy

Thanks for the input Andrew. I'll keep an eye out for this.
